WebVTT
WebVTT (Web Video Text Tracks) is a W3C standard format for displaying timed text tracks, such as subtitles or captions, in web-based video players. It uses a simple text-based syntax with cues that specify timing and text content, making it widely supported by HTML5 video elements and modern browsers. This format enhances video accessibility and localization by allowing developers to add synchronized text overlays to video content.
Developers should learn WebVTT when building video-rich web applications that require subtitles, captions, or other timed text for accessibility compliance (e.g., WCAG) or multilingual support. It is essential for streaming platforms, educational sites, and any project where video content needs to be accessible to diverse audiences, including those with hearing impairments or non-native speakers.
